This is incredibly intriguing, and I'm a bit confused as to why Brian isn't narrating his own book, as usual. The only other time another narrator has read a BJ book occurred in releases of Redwall, Mossflower, and Mariel of Redwall by Recorded Books. At that time, the narrator was Ron Keith.

It completely detracts from the listening experience. Also noteworthy, the Blacksheep UK cover is used. Furthermore, it appears as if this release is strictly digital.

To demonstrate the difference, you can listen to the samples from Brian narrating, and Stuart narrating below.
